POWDER BOX.

Application ledovember l2, 1,921. Serial No. 514,506.

To all whom t may concern.'

Be it known that I, JOHN D. MCFARMND, a citizen of the United States ofAmerica, residing yat the city of St. Louis, State of Missouri, haveinventeda certain new and useful Powder Box, of whichV the following` issuch a full, clear, and exactA description as will enable any oneskilled in the art to which it appertains to make and use the same,referencebeing had to the accompanying drawings, lforming part of thisspecification. i Y

Boxes for containing `face powder are usually made of paper in.cylindrical form, the bo-x being composed of a body and lid tclescopingtogether and the lid usually being` domed'to enhance the appearance ofthe g box. It has been found in practice that it is impossible toproduce such va box inwhich the fit between thel lid and body will besuliiciently tight to prevent the escape of the contents. This"difficulty is increased by the domed form of the lid as this causes theboxto actas bellows whenpressure is applied to the lid thus forcing airout of thev box and carrying powder with it.

, As far as I am aware the only eective form of box for overcoming thisdi'iiiculty is what is'known as a drum box in which a thin piece ofpaper is pasted over the top of the box body. Thisk constructionnecessitates the filling of the box from ythe bottom, the base of thebox being afterwards pasted in position. l Not only is this processexpensive but such a box is effective only when in transit or in thehands of the dealer, for as soon as the thin paper is removed` which itis necessary to do to reach the contents of the box, the effectivenessof the b'ox is destroyed so that in the hands of the user it has thesame objection as the ordinary form of box.

It is the object of my invention to provide a simple and inexpensive boxin which the aforesaid difficulties are overcome so that the. box may befilled in the usual manner" and will prove effective in preventing theescape of powder not only when the box is in transit and in the hands ofthe dealer but also when in the hands of the user.

In the accompanying drawings which illustrate some forms of boxes madein accordance with my invention, Figure 1 is a vertical central sectionon a slightly reduced scale; Figure 2 is a bottom plan view of the lid;Figure 3 is a vertical section through one side of a box showing aslight modification and Figure 4 is a view similar to Fig-` ure 3showing` a further modification.`

5 indicates the body of my box which is cylindrical in form and made ofpaper. This box body 5 is provided with an upwardly extending flange 6.7 is a lid of the box provided with a downwardly extending flange y8 ofsuch size as to telescope with the flange 6 The lid 7 may yloe in theusual manner. either domed as shown in Figures land 3 or flat as showninFlgure 4.

ln carrying` out my invention, I provide the lid 7`with what l term areinforcing member, which member forms, together with iiange 8, all-shaped annular groove'into fmL which the upper edge of the flange 6is i forced to form an impervious joint.' -'This reinforcing memberconsists in a discy 9 hav'- inga beveled edge 10. y, The large diameter`of this disc 9 is equal to the internal diameter of the flange 8 so thatthe disc is accurately seated in the llid concentric with the fiangewhen it is placed in position. The small diameter of the disc issomewhat less than the internal diameter ofthe iiange 8 so that theJ-shaped groove thus formed will receive the said flange .6 when thecover is placed in position on the box. f y

The disc 9' be made of any suitable material but I=prefer to make it ofthat class of card board known inthe trade as I pulp board, as suchboard is slightly yield-` ing in character andassists in the forming ofan impervious joint. The disc 9 may be applied to the lid by pasting' itdirectly to the outer edge of the domed top as shown at ll (Figure 3) orin case the top is notl domed it may be placed against the entire lowerface of the lid Aas shown in Figure 4.. l prefer, however, when the lidis domed to provide it with an annular spacing mem-v ber l2, shown inFigure l, which member` is'pasted against the inner ,face ofA the upperpart of the lid and provides an annularv ledge against which the disc 12may be pasted, thus not only providing a fiat .and level surface againstwhich to secure the disc 9 but also enablingl users of the present formof drum box to substitute a box of my construction which will containthe same l amount of powder without decrcasingrif the size ofthe box andthus the apparent amount of powder sold. l

lJVhen the lid of my box is placed in position upon the box body,l theupper edge of the flange G will be forced between the converging sidesof the annular ll-shaped groove formed between the beveled edge of thedisc 9 and the flange 8 thus compressing the upper edge of the flange (3and securing an impervious joint, which action is assisted by theyielding nature of the disc 9. lt will be evident therefore that my boxwill prevent the escape of the powder' not only during transit and inthe hands of the dealer but will be equally effective in the hands ofthe user.

llfhile l have described my box as cylindrical in form, l wish it to beunderstood that l do not wish to limit myself to such forni except wherespecifically stated in the claims as the box may be made square, val orvother suitable form,

liar/*ing fully described my invention what l claim as new and desire tosecure by Letters Patent of the United States is:

l. ln a device of the class described. the combination with a box bodyhaving an upwardly extending flange, of a lid having a downwardlyextending flange telesconing with said first named flange, and memberforming with onekof said flanges a lf-shaped groove into which the otherof said flanges is adapted to be forced to form an impervious joint.

2. lin a device of the class described, the

combination with a box body having an upwardly extending flange, of alid having 'downwardly extendingflange surrounding said first namedflange, and a re-inforciug with said first named flange, and an internalre-inforcing member having a beveled edge and forming with one of saidflanges a vshaped groove into which the other of said flanges is adaptedto be forced to form an impervious joint.

4f. ln a device of the class described, the combination with acylindrical box bod): having an upwardly extending flange, of a lid forsaid body having a downwardly extending flange surrounding said firstnamed flange, and a. disc secured in said lid and forming with theflange thereon a V- shaped annular groove adapted to receive the flangeon the body and to form there with an impervious joint.

5. ln a device of the class described, the combination with acylindrical box body having an upwardly extending flange. of a lid forsaid body having a downwardl)Y cxtendingflange surrounding said firstnamed flange, and a disc havinga beveled edge, said disc being securedin said lid and forming with the flange thereon a ll-'shaped annulargroove adapted to receive the flange on said body and form there *ith animpervious joint.

6. ln. a device ofthe class described. thel combination with acylindrical box body havingan upwardly extending flange, of a lid forsaid body having a downwardly extending flange surrounding saidv firstnamed flange, an annular spacing member in said lid, and disc providedwith a. beveled edge, said disc being situated in said lid and securedagainst the lower edge of said spacing member', whereby an annularVeshaped groove is formed between said disc and to receive the flange onthe box body and to form therewith an impervious lioint.

ln testimony whereof, l have hereunto set my vhand and affixed my seal.
